Description

Technical Field

[0001] The invention relates to the technical field of wheel hub forging, in particular to an aluminum alloy wheel hub forging device. Background Art

[0002] The manufacturing methods of wheel hubs are divided into casting and forging. Casting can be simply summarized as injecting aluminum liquid into a sand core mold and waiting for it to cool into shape. The casting process is simple, but the strength of the wheel hub manufactured is far less than that of the wheel hub manufactured by the forging process. Forging is to put a metal billet into a mold and use a forging press to apply high-intensity pressure to the metal billet, so that the metal billet undergoes plastic deformation under pressure and finally reaches the required shape. Forging can eliminate defects such as cast looseness produced in the metal smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal streamlines, the mechanical properties of the forged wheel hub are better than those of castings of the same material, making the forged wheel hub strong and durable.

[0003] A Chinese patent discloses a new energy vehicle wheel hub forging device, the patent application number is CN202011585559.7, a new energy vehicle wheel hub forging device, including a base, a first fixed plate fixedly connected to the outer wall of the base, a second fixed plate fixedly connected to the outer wall of the first fixed plate, a lower die fixedly connected to the outer wall of the base, a demolding mechanism is provided on the lower die, a motor is provided on the first fixed plate, a first rotating shaft is fixedly connected to the output end of the motor, a first pulley and a wheel disc are fixedly connected to the first rotating shaft, an eccentric shaft is fixedly connected to the outer wall of the wheel disc, a crank is rotatably connected to the eccentric shaft, an end of the crank away from the eccentric shaft is rotatably connected to a die base, the die base is slidably connected to the second fixed plate, an upper die is fixedly connected to the outer wall of the die base, and a heat dissipation mechanism is provided on the first fixed plate.

[0004] The above-mentioned comparative patent uses a fan to cool the processed wheel hub, and uses the wind force of the fan to blow away the debris generated by processing the metal blank. When forging the wheel hub, the metal blank needs to be heat-treated first to improve the ductility of the metal blank. After the metal blank is heat-treated, the metal blank is placed under the forging press for forging by mechanical clamping. The above-mentioned comparative patent uses a fan to blow away the debris generated by the forging press in the process of forging the wheel hub. The air fanned by the fan can easily reduce the temperature of the heated metal blank to below the preheating value. The drop in the temperature of the metal blank causes the ductility of the metal blank to decrease, increasing the working pressure of the forging press. At the same time, because the ductility of the metal blank deteriorates, the forging press processes the metal blank into a wheel hub under strong pressure, which can easily cause fractures inside the processed wheel hub, resulting in a reduction in the product yield.

[0005] Therefore, an aluminum alloy wheel forging device is proposed. Summary of the invention

[0006] The object of the present invention is to provide an aluminum alloy wheel hub forging device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an aluminum alloy wheel hub forging device, wherein a rectangular groove is provided on the front end outer surface of the main body, a workbench is fixedly installed on the inner lower end outer surface of the rectangular groove, a hydraulic head is arranged at the center position of the inner upper surface of the rectangular groove, and the upper end of the hydraulic head is slidably connected to the main body; a wheel hub mold is fixedly connected to the center position of the upper end outer surface of the workbench, three groups of arc plates are evenly fixedly installed in an annular shape on the upper end outer surface of the workbench near the wheel hub mold, and a plurality of flame spraying mechanisms are evenly fixedly installed on the outer surface of one side of the arc plate in an arc shape;

[0008] The flame-spraying mechanism comprises a cylinder, an air inlet, a gas pipeline, a dispersion hole, a horizontal plate, a support rod and metal blades; the outer surface of one side of the arc-shaped plate is arc-shaped and a plurality of cylinders are evenly fixedly installed, the middle positions of both sides of the outer surface of the cylinder are provided with air inlet holes, a support rod is fixedly installed on the inner wall of the upper end of the cylinder, a metal blade is rotatably installed on the center position of the outer surface of the upper end of the support rod, a horizontal plate is fixedly installed on the inner wall of the lower end of the cylinder, a plurality of dispersion holes are penetrated through the upper surface of the horizontal plate, and a gas pipeline is provided on the inner wall of the cylinder below the horizontal plate.

[0009] The fan blows away the debris generated by the forging machine during the forging process of the wheel hub in the comparative patent. The air blown by the fan can easily cause the temperature of the heated metal blank to drop to too much of the preheating value. The drop in the temperature of the metal blank leads to a decrease in the ductility of the metal blank, which increases the working pressure of the forging machine. At the same time, because the ductility of the metal blank deteriorates, the forging machine processes the metal blank into the wheel hub under strong pressure, which can easily cause fractures inside the processed wheel hub, resulting in a decrease in the product yield. The hydraulic head of the present invention first introduces gas into the gas pipeline before the metal ingredients in the forging wheel hub mold are mixed. The gas enters the cross plate along the gas pipeline and is dispersed into several gas columns by several dispersion holes on the cross plate, so that the gas is fully in contact with the air, so that the subsequent gas can be fully burned. The gas flows through the interior of the cylinder at a high speed. Because the flow rate is large and the internal pressure of the cylinder is small, the air around the cylinder is pressed into the interior of the cylinder through the air inlet by the air pressure, so that the gas is further mixed with the air, so that the subsequent The gas on the surface can be further fully burned when it burns. When the gas flows to the metal fan blades, it will push the metal fan blades to rotate. The rotating metal fan blades will evenly disperse the gas to make it fan-shaped. The gas is ignited by the igniter, and the flame will also be fan-shaped, increasing the heating area when forging the metal billet. At the same time, the metal fan blades will also be heated to a red-hot state. Even if the flame at the flame-throwing mechanism is extinguished during operation, the gas will be ignited again due to the high temperature of the metal fan blades, ensuring that the flame-throwing mechanism can work normally, so that it can always maintain the preheating temperature when forging the metal billet, thereby maintaining the ductility of the metal billet. The flame-throwing mechanism cooperates with the arc plate to make the flame-throwing mechanism evenly distributed around the metal billet, so that the metal billet is evenly heated, so that the various positions of the metal billet can maintain good ductility, avoiding the problem of increased working pressure of the forging press due to reduced ductility of the metal billet. At the same time, the ductility of the metal billet is well maintained, which also improves the yield rate of wheel forging.

[0010] Preferably, a baffle plate is provided inside the connection between the arc plate and the flamethrower mechanism, a first rotating rod is fixedly installed on one side of the outer circular surface of the baffle plate, one end of the first rotating rod is rotatably connected to the inner wall of the gas pipeline; a second rotating rod is fixedly installed on the other side of the outer circular surface of the baffle plate, one end of the second rotating rod is fixedly connected to a first spring, one end of the first spring is fixedly connected to the inside of the arc plate, a trigger rod is fixedly connected to the upper end position of the outer circular surface of the baffle plate, a cavity is provided inside the arc plate near the trigger rod, a spring sheet is provided on one side of the cavity, the upper outer surface of the spring sheet is fixedly connected to the first signal line, a receiving sheet is fixedly installed inside the arc plate near the spring sheet, the upper outer surface of the receiving sheet is fixedly connected to the second signal line.

[0011] During operation, due to blockage or damage of individual flamethrower mechanisms, the flamethrower mechanisms cannot spray flames normally, thereby affecting the heating of the metal blank, resulting in uneven heating of the metal blank. The temperature of some positions of the metal blank is lower than the temperature during preheating, resulting in uneven ductility of the metal blank, which can easily lead to a decrease in the yield of wheel hub forging. In addition, each flamethrower mechanism is numbered in advance and entered into the system in the main body. If one of the flamethrower mechanisms is extinguished, the flames sprayed by the flamethrower mechanisms on the adjacent two sides can easily cover the extinguished flamethrower mechanism, making it difficult for the extinguished flamethrower mechanism to be observed by the staff. When the flamethrower mechanism of the present invention is blocked or damaged, the gas in the damaged flamethrower mechanism does not flow, and the gas cannot push the baffle plate (when the gas flows, the baffle plate will be pushed to a vertical state by the gas to deform the first spring, which does not hinder the flow of gas during operation). Because the first The contraction force of the spring pulls the baffle plate to a horizontal state, so that the trigger rod on the baffle plate pushes the spring sheet, so that the spring sheet contacts the receiving sheet, and the first signal line is connected to the second signal line. The system receives the information that the signal is connected and can determine which flamethrower has a problem. A warning pops up on the operation panel about which flamethrower has a problem, prompting the staff to replace or repair it (the controller in the main body is set to determine that the flamethrower has a problem when the first signal line and the second signal line are connected and the time is seconds. The second is the delay time, and the delay time can also be determined according to the situation. The delay time is to avoid misleading information caused by popping up a warning on the operation panel when the flamethrower is turned on and the gas is not yet ventilated and the signal line is in a connected state), avoiding the problem of regular staff inspection of the flamethrower mechanism and reducing the workload of the staff.

[0012] Preferably, a prism is fixedly connected to the outer surface of the lower end of the cylinder, a sealing ring is provided at the edge of the lower end surface of the prism, a threaded tube is fixedly installed at the center of the outer surface of the lower end of the prism, and the threaded tube is threadedly connected to the arc plate.

[0013] During operation, when the flame-spraying mechanism is detected to be damaged or blocked by the above-mentioned detection component, it is necessary to disassemble the flame-spraying mechanism. In the present invention, the operator uses a wrench to twist the prism to loosen the threaded tube and the arc plate, thereby easily removing the flame-spraying mechanism (because the cylinder in the flame-spraying mechanism is fixedly connected to the prism), and then the flame-spraying mechanism is repaired and replaced. The sealing ring is used to ensure the airtightness of the installation location when installing the flame-spraying mechanism to prevent the gas from leaking out through the installation location.

[0014] Preferably, a moving block is fixedly installed at the center position of the outer surface of one side of the arc plate, an arc block is fixedly installed near the center position on the upper outer surface of the moving block, an L-shaped pull rod is slidably connected to the center position of the upper outer surface of the moving block, one end of the L-shaped pull rod is rotatably connected to a connecting rod, a fixed rod is fixedly connected to the lower outer surface of the connecting rod, a blocking disk is fixedly installed on the outer surface of the connecting rod near the lower end, a second spring is connected to the outer surface of the connecting rod by a knot, three groups of slide grooves are evenly opened on the outer surface of the upper end of the workbench in a ring-shaped manner, a plurality of bevel teeth are evenly fixedly installed on the inner bottom of the slide groove, and the lower end of the fixed rod is an oblique cross-section and is engaged with the bevel teeth.

[0015] During operation, because it is necessary to forge wheel hubs of different sizes, it is necessary to adjust the position of the arc plate, and at the same time, the position of the flame-spraying mechanism is also adjusted. When the movable block is pulled toward the edge of the workbench, because the lower end inclined surface of the fixing rod is consistent with the inclination angle of the bevel gear, when the movable block is pulled, the fixing rod moves upward, and at the same time, the connecting rod is pulled upward, driving the second spring to compress. After the fixing rod moves past one bevel gear, the rebound force of the second spring pushes the blocking plate to move downward, and at the same time drives the connecting rod and the fixing rod to move downward, so that the fixing rod is engaged with the two bevel gears, so that the movable block can be pulled to any position of the slide slot and can be fixed and stopped. When the movable block is pulled in the opposite direction, the L-shaped pull rod is pulled and rotated, and then the L-shaped pull rod is placed on the arc block, so that the fixing rod is separated from the two bevel gears, thereby easily pushing the movable block in the opposite direction, thereby realizing the adjustment of the arc plate and the flame-spraying mechanism, and realizing that the arc plate and the flame-spraying mechanism can be suitable for the processing of wheel hubs of different sizes, thereby improving the practicality of the present invention.

[0016] Preferably, a scale line is provided on the outer surface of the upper end of the workbench near one side of the slide groove, and an indicator line is provided at the center position of the outer surface of one side of the moving block for indicating the value on the scale line.

[0017] During operation, in order to ensure that the adjusted position of each moving block is consistent when adjusting the arc plate and the flame-spraying mechanism, the present invention moves the moving block to the desired position when adjusting the moving block, observes the value pointed to by the indicator line on the moving block on the scale line and records it, and when adjusting the lower moving block, it is only necessary to align the indicator line on the moving block with the value just recorded on the scale line, thereby improving the adjustment accuracy of the arc plate and the flame-spraying mechanism.

[0018] Preferably, a brush handle is fixedly mounted on the outer surface of one side of the moving block, and a brush is fixedly mounted on the outer surface of the lower end of the brush handle for cleaning impurities in the chute.

[0019] During operation, some dust and impurities may enter the slide groove and hinder the movement of the moving block. The present invention installs a brush handle on the moving block and installs a brush under the brush handle so that the brush can clean the slide groove when the moving block is moved, thereby making it easier to adjust the moving block.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention is heated to a red-hot state when the metal fan blades are working. Even if the flame at the flame-throwing mechanism is extinguished during operation, the high temperature of the metal fan blades will ignite the gas again, ensuring that the flame-throwing mechanism can work normally, so that it can always maintain the preheating temperature when forging the metal billet, thereby maintaining the ductility of the metal billet. The flame-throwing mechanism cooperates with the arc plate to make the flame-throwing mechanism evenly distributed around the metal billet, so that the metal billet is evenly heated, so that the various positions of the metal billet can maintain good ductility, avoiding the problem of increased working pressure of the forging press due to reduced ductility of the metal billet. At the same time, the ductility of the metal billet is well maintained, and the yield rate of wheel hub forging is also improved.

[0022] 2. When the gas in the damaged flamethrower mechanism stops flowing, the gas cannot push the baffle plate, so that the first signal line and the second signal line are connected for a long time, and the trigger system sends a warning prompt to the staff, prompting the staff to replace or repair the flamethrower mechanism, thereby avoiding the problem of regular inspection of the flamethrower mechanism by the staff and reducing the workload of the staff.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] See also Figures 1 to 12 The present invention provides a technical solution for aluminum alloy wheel forging equipment:

[0040] An aluminum alloy wheel forging device, such as Figures 1 to 4 As shown, it comprises a main body 1, a rectangular groove 23 is provided on the front end outer surface of the main body 1, a workbench 2 is fixedly installed on the inner lower end outer surface of the rectangular groove 23, a hydraulic head 3 is arranged at the center position of the inner upper surface of the rectangular groove 23, and the upper end of the hydraulic head 3 is slidably connected to the main body 1; a hub mold 4 is fixedly connected to the center position of the upper end outer surface of the workbench 2, three groups of arc plates 5 are evenly fixedly installed in an annular shape on the upper end outer surface of the workbench 2 near the hub mold 4, and a plurality of flame-spraying mechanisms 6 are evenly fixedly installed on the outer surface of one side of the arc plate 5 in an arc shape;

[0041] The flame-spraying mechanism 6 includes a cylinder 61, an air inlet 62, a gas pipeline 63, a dispersion hole 64, a horizontal plate 65, a support rod 66, and a metal fan blade 67; the outer surface of one side of the arc plate 5 is arc-shaped and evenly fixed with a plurality of cylinders 61, and the middle positions of both sides of the outer surface of the cylinder 61 are provided with air inlet holes 62, and the upper inner wall of the cylinder 61 is fixedly provided with a support rod 66, and the metal fan blade 67 is rotatably installed at the center position of the upper outer surface of the support rod 66, and the lower inner wall of the cylinder 61 is fixedly provided with a horizontal plate 65, and the upper surface of the horizontal plate 65 is penetrated with a plurality of dispersion holes 64, and the inner wall of the cylinder 61 is provided with a gas pipeline 63 below the horizontal plate 65.

[0042] In contrast, in the patent, a fan is used to blow away the debris generated by the forging press during the forging process of the wheel hub. The air blown by the fan can easily cause the temperature of the heated metal blank to drop to too much of the preheating value. The drop in the temperature of the metal blank leads to a decrease in the ductility of the metal blank, which increases the working pressure of the forging press. At the same time, because the ductility of the metal blank deteriorates, the forging press processes the metal blank into the wheel hub under strong pressure, which can easily cause fractures inside the processed wheel hub, resulting in a decrease in the product yield. Before the hydraulic head 3 of the present invention forges the metal ingredients in the wheel hub mold 4, the gas is first introduced into the gas pipeline 63. The gas enters the horizontal plate 65 along the gas pipeline 63 and is dispersed into several gas columns by the several dispersion holes 64 on the horizontal plate 65, so that the gas is fully in contact with the air, so that the subsequent gas can be fully burned when it is burned. The gas flows through the inside of the cylinder 61 at a high speed. Because the flow rate is large and the internal pressure of the cylinder 61 is small, the air around the cylinder 61 is pressed into the inside of the cylinder 61 by the air pressure through the air inlet 62, so that the gas is further mixed with the air The combination makes the following gas burn more fully. When the gas flows to the metal blades 67, it will push the metal blades 67 to rotate. The rotating metal blades 67 will evenly disperse the gas to make it fan-shaped. When the gas is ignited by the igniter, the flame will also be fan-shaped, increasing the heating area when forging the metal billet. At the same time, the metal blades 67 will also be heated to a red-hot state. Even if the flame at the flame-throwing mechanism 6 is extinguished during operation, the gas will be ignited again due to the high temperature of the metal blades 67, ensuring that the flame-throwing mechanism 6 can work normally, so that it can always maintain the preheating temperature when forging the metal billet, thereby maintaining the ductility of the metal billet. The flame-throwing mechanism 6 cooperates with the arc plate 5 to make the flame-throwing mechanism 6 evenly distributed around the metal billet, so that the metal billet is evenly heated, so that the various positions of the metal billet can maintain good ductility, avoiding the problem of increased working pressure of the forging press due to reduced ductility of the metal billet. At the same time, the ductility of the metal billet is well maintained, and the yield rate of wheel hub forging is also improved.

[0043] As an embodiment of the present invention, Figures 1 to 8As shown, a baffle plate 7 is provided inside the connection between the arc plate 5 and the flamethrower mechanism 6, a first rotating rod 71 is fixedly installed on one side of the outer circular surface of the baffle plate 7, and one end of the first rotating rod 71 is rotatably connected to the inner wall of the gas pipeline 63; a second rotating rod 72 is fixedly installed on the other side of the outer circular surface of the baffle plate 7, one end of the second rotating rod 72 is fixedly connected to a first spring 8, one end of the first spring 8 is fixedly connected to the inside of the arc plate 5, a trigger rod 73 is fixedly connected to the upper end position of the outer circular surface of the baffle plate 7, a cavity 9 is opened in the interior of the arc plate 5 near the trigger rod 73, a spring sheet 10 is provided on one side of the cavity 9, a first signal line 11 is fixedly connected to the upper outer surface of the spring sheet 10, a receiving sheet 13 is fixedly installed in the interior of the arc plate 5 near the spring sheet 10, and a second signal line 12 is fixedly connected to the upper outer surface of the receiving sheet 13.

[0044] During operation, due to blockage or damage of individual flamethrower mechanisms 6, the flamethrower mechanisms 6 cannot spray flames normally, thereby affecting the heating of the metal blank, resulting in uneven heating of the metal blank. The temperature of some positions of the metal blank is lower than the temperature during preheating, resulting in uneven ductility of the metal blank, which can easily lead to a decrease in the yield of wheel hub forging. In addition, each flamethrower mechanism 6 is numbered in advance and entered into the system in the main body 1. If one of the flamethrower mechanisms 6 is extinguished, the flames sprayed by the flamethrower mechanisms 6 on the adjacent two sides can easily cover the extinguished flamethrower mechanism 6, resulting in the extinguished flamethrower mechanism 6 being difficult to be observed by the staff. When the flamethrower mechanism 6 of the present invention is blocked or damaged, the gas in the damaged flamethrower mechanism 6 does not flow, and the gas cannot push the baffle plate 7 (when the gas flows, the baffle plate 7 will be pushed to a vertical state by the gas to deform the first spring 8, which does not hinder the flow of gas during operation). Because the contraction force of the first spring 8 The blocking plate 7 is pulled to a horizontal state, so that the trigger rod 73 on the blocking plate 7 pushes the spring sheet 10, so that the spring sheet 10 contacts the receiving plate 13, and the first signal line 11 is connected to the second signal line 12. The system receives the information of the signal connection and can determine which flame-spraying mechanism 6 has a problem. A warning pops up on the operation panel about which flame-spraying mechanism 6 has a problem, prompting the staff to replace or repair it (the controller in the main body 1 is set to determine that the flame-spraying mechanism 6 at that location has a problem when the first signal line 11 and the second signal line 12 are connected and the time is 30 seconds. The 30 seconds is the delay time, and the delay time can also be determined according to the situation. The delay time is to avoid misleading information caused by popping up a warning on the operation panel when the flame-spraying mechanism 6 is turned on and the gas is not yet ventilated and the signal line is in a connected state), thereby avoiding the problem of regular staff checking of the flame-spraying mechanism 6 and reducing the workload of the staff.

[0045] As an embodiment of the present invention, Figure 3 to Figure 4As shown, a prism 14 is fixedly connected to the outer surface of the lower end of the cylinder 61, a sealing ring 15 is provided at the edge of the lower end surface of the prism 14, a threaded tube 16 is fixedly installed at the center of the outer surface of the lower end of the prism 14, and the threaded tube 16 is threadedly connected to the arc plate 5.

[0046] During operation, when the flame-spraying mechanism 6 is detected to be damaged or blocked by the above-mentioned detection component, it is necessary to disassemble the flame-spraying mechanism 6. In the present invention, the operator uses a wrench to twist the prism 14 to loosen the threaded tube 16 and the arc plate 5, thereby easily removing the flame-spraying mechanism 6 (because the cylinder 61 in the flame-spraying mechanism 6 is fixedly connected to the prism 14), and then the flame-spraying mechanism 6 is repaired and replaced. The sealing ring 15 is used to ensure the airtightness of the installation location when installing the flame-spraying mechanism 6 to prevent the gas from leaking out through the installation location.

[0047] As an embodiment of the present invention, Figures 9 to 12 As shown, a moving block 17 is fixedly installed at the center position of the outer surface of one side of the arc plate 5, and an arc block 171 is fixedly installed on the upper outer surface of the moving block 17 near the center position, an L-shaped pull rod 172 is slidably connected to the center position of the upper outer surface of the moving block 17, one end of the L-shaped pull rod 172 is rotatably connected to a connecting rod 174, and a fixing rod 176 is fixedly connected to the lower outer surface of the connecting rod 174, and a blocking plate 175 is fixedly installed on the outer surface of the connecting rod 174 near the lower end, and a second spring 173 is connected to the outer surface of the connecting rod 174 by a knot, and three groups of slide grooves 18 are evenly opened on the outer surface of the upper end of the workbench 2 in an annular shape, and a plurality of oblique teeth 181 are evenly fixedly installed on the inner bottom of the slide groove 18, and the lower end of the fixing rod 176 is an oblique cross-section and is engaged with the oblique teeth 181.

[0048] During operation, because it is necessary to forge wheels of different sizes, it is necessary to adjust the position of the arc plate 5, and at the same time, the position of the flame-spraying mechanism 6 is also adjusted. When the present invention pulls the moving block 17 toward the edge of the workbench 2, because the lower end inclined surface of the fixing rod 176 is consistent with the inclined angle of the beveled tooth 181, when the moving block 17 is pulled, the fixing rod 176 moves upward, and at the same time, the connecting rod 174 is pulled upward, driving the second spring 173 to compress. After the fixing rod 176 moves past one beveled tooth 181, the rebound force of the second spring 173 pushes the blocking plate 175 downward, and at the same time drives the connecting rod 174 and the fixing rod 176 to move downward. The fixed rod 176 moves downward, so that the fixed rod 176 is engaged with the two bevel teeth 181, so that the movable block 17 can be pulled to any position of the slide groove 18 and can be fixed and stopped. When the movable block 17 is pulled in the reverse direction, the L-shaped pull rod 172 is pulled and rotated, and then the L-shaped pull rod 172 is placed on the arc block 171, so that the fixed rod 176 and the two bevel teeth 181 are separated, so that the movable block 17 is easily pushed in the opposite direction, thereby realizing the adjustment of the arc plate 5 and the flamethrower mechanism 6, and realizing that the arc plate 5 and the flamethrower mechanism 6 can be suitable for the processing of wheel hubs of different sizes, thereby improving the practicality of the present invention.

[0049] As an embodiment of the present invention, Fig. 9 and Fig.12 As shown, a scale line 19 is provided on the outer surface of the upper end of the workbench 2 near the slide groove 18 , and an indicator line 22 is provided at the center of the outer surface of one side of the moving block 17 for indicating the value on the scale line 19 .

[0050] During operation, in order to ensure that the adjusted position of each moving block 17 is consistent when adjusting the arc plate 5 and the flame-spraying mechanism 6, the present invention moves the moving block 17 to the desired position when adjusting the moving block 17, observes the value pointed to by the indicator line 22 on the moving block 17 on the scale line 19 and records it, and when adjusting the lower moving block 17, it is only necessary to align the indicator line 22 on the moving block 17 with the value just recorded on the scale line 19, thereby improving the adjustment accuracy of the arc plate 5 and the flame-spraying mechanism 6.

[0051] As an embodiment of the present invention, Fig.10 As shown, a brush handle 20 is fixedly mounted on the outer surface of one side of the moving block 17 , and a brush 21 is fixedly mounted on the outer surface of the lower end of the brush handle 20 for cleaning impurities in the chute 18 .

[0052] During operation, some dust and impurities may enter the slide groove 18 and hinder the movement of the moving block 17. The present invention installs a brush handle 20 on the moving block 17 and installs a brush 21 under the brush handle 20, so that the brush 21 can clean the slide groove 18 when the moving block 17 is moved, thereby making it easier to adjust the moving block 17.

[0053] Method of use: Before the hydraulic head 3 of the present invention forges the metal ingredients in the wheel hub mold 4, the gas is first introduced into the gas pipeline 63. The gas enters the horizontal plate 65 along the gas pipeline 63 and is dispersed into a plurality of gas columns by the plurality of dispersion holes 64 on the horizontal plate 65, so that the gas is fully in contact with the air, so that the subsequent gas can be fully burned. The gas flows through the cylinder 61 at a high speed. Because the flow rate is large and the internal pressure of the cylinder 61 is small, the air around the cylinder 61 is pressed into the cylinder 61 through the air inlet 62 by the air pressure, so that the gas is further mixed with the air, so that the subsequent gas can be further fully burned. When the gas flows to the metal fan blades 67, it will push the metal fan blades 67 to rotate. The rotating metal fan blades 67 will evenly disperse the gas to make the gas fan-shaped, through When the igniter ignites the gas, the flame will also be fan-shaped, increasing the heating area when forging the metal billet, and the metal fan blades 67 will also be heated to a red-hot state. Even if the flame at the flame-throwing mechanism 6 is extinguished during operation, the high temperature of the metal fan blades 67 will ignite the gas again, ensuring that the flame-throwing mechanism 6 can work normally, so that it can always maintain the preheating temperature when forging the metal billet, thereby maintaining the ductility of the metal billet. The flame-throwing mechanism 6 cooperates with the arc plate 5 to make the flame-throwing mechanism 6 evenly distributed around the metal billet, so that the metal billet is evenly heated, so that the ductility of the metal billet can be maintained at all positions, avoiding the problem of increased working pressure of the forging press due to reduced ductility of the metal billet. At the same time, the ductility of the metal billet is well maintained, which also improves the yield rate of wheel hub forging.

[0054] When the flame spraying mechanism 6 of the present invention is blocked or damaged, the gas in the damaged flame spraying mechanism 6 does not flow, and the gas cannot push the blocking plate 7 (when the gas flows, the blocking plate 7 will be pushed to a vertical state by the gas to deform the first spring 8, and will not hinder the flow of gas during operation). Because the contraction force of the first spring 8 pulls the blocking plate 7 to a horizontal state, the trigger rod 73 on the blocking plate 7 pushes the spring sheet 10, so that the spring sheet 10 contacts the receiving sheet 13, so that the first signal line 11 is connected with the second signal line 12. The system receives the information of the signal connection and can determine which flame spraying mechanism 6 has a problem, and a pop-up message of which flame spraying mechanism 6 is displayed on the operation panel. The flame spray mechanism 6 is warned of a problem, prompting the staff to replace or repair it (the controller in the main body 1 is set to determine that the flame spray mechanism 6 at that location has a problem when the first signal line 11 and the second signal line 12 are connected and the time is 30 seconds. The 30 seconds is the delay time, and the delay time can also be determined according to the situation. The delay time is to avoid misleading information caused by pop-up warnings on the operation panel when the flame spray mechanism 6 is turned on and the gas is not yet ventilated and the signal line is in the connected state), thereby avoiding the problem of regular staff inspection of the flame spray mechanism 6 and reducing the workload of the staff.
